We put one in our first TT - big mistake! The first time we took the TT out, none of the electricity worked on that side of the TT. No lights, no power, nada. Turns out, there were wires running under the cabinet, as noted by edcronin01, and we just happened to drill through one when installing the coffee maker. Turned out to be a $142 coffee pot.
